Innovative Influenza Chemotherapeutics Targeting Polymerase Nuclear Import ID: 2017-004

This technology introduces a novel approach to influenza treatment by inhibiting the nuclear import of the virus's polymerase, offering a promising avenue for developing effective antivirals.

Technology Overview

The technology focuses on the development of new antiviral drugs that target the influenza virus by binding the PB1 subunit of its polymerase at a conserved site. This mechanism is designed to reduce viral replication and the emergence of resistance by directly targeting the virus, potentially leading to more effective treatments with minimized toxicity. Preliminary experiments have identified two compounds, ASN-D and LAS-T, that show selective efficacy against various influenza strains, with opportunities for further optimization.

Key Advantages

• Direct targeting of the influenza virus, potentially reducing the emergence of drug resistance
• Identification of two promising compounds with selective efficacy against multiple influenza strains
• Lower toxicity by avoiding targeting of host proteins
• Potential for inclusion in a multi-drug regimen, enhancing treatment robustness

Problems Addressed

• High mutation rate of the flu virus leading to resistance against current treatments
• Lack of effective antiviral drugs with novel mechanisms of action
• Need for treatments with lower toxicity and reduced side effects

Market Applications

• Development of new classes of antiviral drugs for influenza
• Strategic licensing opportunities, particularly in the US and Asia
• Complement to existing influenza treatments, potentially as part of a multi-drug regimen
